Prime Property Compound Interest Game Game Play: Players compete against one another to amass the most wealth over a predetermined number of laps around the board. Whilst buying property is secure its value will not increase or decrease. Only cash balances will fluctuate due to compound interest. All players begin at the square labelled ‘Start’. Each player begins with \$100 Each player will role the dice and move the required number of places around the board. Each square represents a percentage increase or decrease. The number of places moved represents the number of years of compound interest. Player 1 rolls the dice, moves their counter the required number of spaces and calculates a revised budget.
